Val-Matic’s QuadroSphere Ball Valve features a contoured ball with four recessed surfaces, which is designed to allow solids to be flushed from the body/ball cavity to prevent them from being trapped around the back of the seat rings and bearings. Recessed surfaces on the ball provide lipped edges, which allow the seats to be scraped clean and help prevent buildup of solids and scale. The QuadroSphere maintains resistance across the seating surfaces when cycling, reducing wear, and helping to improve the performance life of the ball and seats.
